Title: Drying of sticky temperature sensitive part-icles
IPC: C04B11/02
Filed: 1970-02-12
Abstract: Moist particles, e.g. separated from a liquid by a centrifuge, which are likely to stick together, cake or prematurely harden, are dried by using a heated gas to pass them along a shaft with heated walls. The particles give up enough moisture to prevent their sticking, and may then be introduced into a further drier. Typically used for drying alpha-CaSO4.1/2 H2O or CaSO4.2H2O.

Title: Niitrilotriacetate soln purification - by heating under pressure and venting while still hot
Filed: 1971-02-08
Abstract: Pure alkali salt solns. of nitrilotriacetic acid are produced by heating a crude alkali nitrilotriacetate soln.

Patent DE-2328959-A1 (DE)
Title: Determination of conductivity of high-temp. slags - using insulated electrodes involves putting one end in contact with slag
Inventor: WEIDEMANN JOHANNES DR ING
IPC: G01N27/06
Filed: 1973-06-07
Abstract: The conductivity may be measured without its being influenced by the depth of immersion of the probe or by the increasing conductivity of the insulation matieral as temp. rises. In the probe, two tube electrodes are arranged concentrically to a centre electrode. The inner tube electrode acts as a screen in dividing the insulating material separating the centre from the outer electrode. The inner and outer tube electrodes are connected to the terminals of a constant voltage source. The centre electrode is interconnected with the inner tube-electrode through a low working resistance, which keeps the potential difference low between them. A display device connected to their terminals shows the voltage drop between them.

Title: Flexible floor for sports halls - has plastics floor plates which are connected to plastic support blocks under the floor
Inventor: HOFMANN LIESELOTTE
IPC: E04F15/22
Filed: 1973-07-14
Abstract: The floor covering plates form integral units with the supporting blocks below. These composite plates are made from rigid foam plastics. The material used for making the floor panels and its supporting blocks can be polystyrene. The plate units can be made by casting or by deep drawing. The edges of the top plate and of the supporting blocks are arranged so that they can be assembled by overlapping and forming narrow gaps. The covering plates can be welded to each other or connected by bolts. The supporting blocks should be relatively small and the top floor plate should be much larger than the supporting block sections. This arrangement is an improvement of the design in which chipboard blocks are used.

Title: I.C. engine magneto ignition system - has high-speed efficiency improved by generating two ignition voltages using magnet and switch
Inventor: HAUBNER GEORG
IPC: F02P1/08
Filed: 1973-12-08
Abstract: The magneto ignition system for internal combustion engines has an E-shaped yoke with a primary and a secondary winding, subjected to magnetic flux from a rotating magnet fixed to the engine shaft etc. The primary is connected over a switch to earth, and the switch is controlled by a speed dependent element. The secondary is connected to the spark plug. The magneto generates two oppositely directed flux changes, one producing a controlled ignition voltage when the switch is opened, and the other producing an uncontrolled ignition voltage, whilst the switch is open. The uncontrolled ignition voltage is used for the engine higher speeds, and improves its efficiency.

Title: Folding support frame for table tops - has central plate joint on which support struts pivot allowing frame to fold
Inventor: LAMBERT PAUL
IPC: F16M11/38
Filed: 1974-03-14
Abstract: The advantage of the design is that the legs when folded occupy a very small space and there is no additional structure on the underside of the table. The two corners of the table are supported by two struts of similar length that meet at a pivoting plate joint. Two individual struts fit below this plate joint in the same parallel plane. The clearance between the two pairs of struts is governed by the thickness of the struts themselves. The connection points to the pivoting plate joint are sufficiently spaced to allow the struts to pivot. The plates of the joint are held together by a bolt in the centre and one of each of the upper and lower struts is butt welded to the plates.

IPC: E01C13/00
Filed: 1974-04-26
Abstract: The device is intended for application to the upper surface of bricks, forming the lateral boundaries of sports grounds, playgrounds, walking-paths, etc. A profile, made of soft PVC or natural rubber is provided, which extends across the length of at least one brick and possesses two arms, directed downwards, for insertion on the shaped bricks. The buffer is sufficiently soft to prevent injuries to falling athletes etc., but is firmly bonded to the shaped bricks. It can be inserted after the construction of the enclosure, if desired, and is, therefore, easily exchangeable.

Title: Locking clip insertion tool for bolts, nuts - has shank and spring loaded lever
Inventor: FISCHER MAX
IPC: B25B27/08
Filed: 1974-06-28
Abstract: The locking section of the safety clip is inserted into a bore of the bolt to be secured. The eye-shaped fastening section of the clip surrounds the bolt, and supports itself elastically against the machine part. The two elements are connected via an elastic wire shackle. The tool has a shank with a grip. The lower tool side carries a trunnion, which may be inserted into the shackle, and a fork shaped support. The support projections point towards the front shank end. With an inserted clip, the projections enclose the locking section and support themselves against the outer edge of the fastening section. The spring-loaded lever is hinged to the shank front, and has a support to press apart the locking and the fastening sections. Between the front shank end and its axial phane, holding the trunnion, is a space which corresponds to the distance between the bore and the end of the nut.

Title: Fishing rod bite indicator - comprises lever with eye for line and sign pivoting on free rod end
Inventor: VERSTEEG KLAAS
IPC: A01K97/12
Filed: 1974-07-18
Abstract: The fact that a fish has bitten is indicated by a lever on the rod end furthest form the angler. The longer and heavier end of the rod has an eye through which the line is threaded, while an indicator is fixed to the other end. The lever can be of wire, bent into a U-shape at the pivot point so as to fit under the pivot pin head. The lever can be bent into an S-shape at the end furthest from the angler, so as to bring the indicator into line with the rod. The pivot pin can pass in succession through a hole in a round plate, the U-section of the lever, a washer and a securing clip holding the lever on it. The plate can be of plastic, its radius being equal to the distance between the pivot point and the S-shaped part of the lever. The pivot pin can be in the form of a rivet, and the indicator in that of a brightly-coloured or luminous plastic spherE.

Title: Room partitioning elements - are joined via plug connector which can be detached
Inventor: LELLE HANS-DIETER DIPL ING
IPC: E06B9/01
Filed: 1974-12-17
Abstract: The plug connector for decorative plastics grillages connects two elements and it can be detached. These decorative open grillages can be used as partitioning elements for rooms and grillages are connected without using any additional connecting elements. The frame part with the plate form locking plug 15 has corners which are cut down halfway leaving an opening so that the other frame half with the matching locking socket 16 and with matching corner cutouts can be pushed into the first frame so that a smooth outline is formed. The plug plate engages with the socket by snap action while the end plates 10 and 13 are suitable deflected. Dismantling is carried out by pushing these end plates apart and sliding the end walls out of engagement.

Title: Ski brake which operates when ski binding is released - has specially coated prongs which are forced into snow
Inventor: SVOBODA JOSEF DIPL ING
IPC: A63C7/10
Filed: 1974-06-20
Abstract: The ski brake (16) is formed from a rod bent into the form of a U with two legs (20). The brake (16) is attached to the ski by a clamping plate (15) which has a transverse groove in its undersurface which fits over a cross member between the legs (20) of the brake (16). The cross member is provided with a torsion spring (18) which tends to rotate the brake (16). When the ski boot is in posn. over the clamping plate (15) this rotation is prevented but as soon as the ski is released from the boot the legs (20) dig into the snow. The ends of the legs are coated and roughened to increase friction with the snow.
